NORTH AMERICAN GEOTRUPINAE — HOWDEN 205 



with a few coarse punctures, heavilji punctate! laterally. Coarse 

 punctures are present in a narrow median band running from the 

 transverse carina of pronotum to the posterior margin. Another band 

 of punctm-es is present at the posterior of the lateral limiting grooves. 

 A second one runs halfway between and parallel to the first band and 

 the posterior margin of pronotum, extending almost to lateral carina. 

 This second band of punctures is in a wide groove, only vaguely 

 indicated in most specimens of E. lazarus lazarus. Minute secondary 

 punctures are extremly small and vague, rather sparsely but evenly 

 scattered over pronotum. Punctures in elytral striae deep, sharply 

 delimited, generally separated by less than their own diameter (pi. 2, 

 fig. 8). Elytral punctures without setae except those on the margins 

 of the elytra and epipleura, where some of the punctures bear long 

 yellowish red setae. Five well developed striae between sutural 

 interval and umbone. All of the intervals between these five striae 

 (pi. 2, fig. 8) with no noticeable difference in their widths. Rows of 

 punctiu'es noted in E. lazarus lazarus in the wider second and fourth 

 intervals are entirely absent in E. lazarus subtropicus. Humerus of 

 elytron bearing a small sharp tubercle at edge. Foremargin of eye 

 canthus noticeably produced forward at outer angle, where it is sharply 

 rounded (pi. 2, fig. 6). The lamellae of the antennal club no longer 

 than eye (pi. 2, fig. 6), noticeably smaller than in E. lazarus lazarus. 

 Also, eye size is slightly smaller than in the usual E. lazarus lazarus. 

 Holotype with clypeal horn about as long as wide, bifid at tip. Poorly 

 developed transverse carina on vertex. Pronotal modification poorly 

 developed, carinae small with lateral limiting grooves shallow. 



Allotype: Female, length 9.3 mm., greatest width 5.8 mm. Dif- 

 fers from the male holotjrpe mainly in the following respects. Clyp- 

 eal horn reduced, smaller than the one on the vertex which is larger 

 than on males. Other than the differences in the horns and a slight 

 difference in size, the female is similar to the male. Shape of eye 

 canthus, antennal size, pronotal modifications, and elytral striae are 

 all similar.
